LOCK.

SPEGIFICATON forming part of Letters Patent No. 343,290, dated June 8,1886.

Application filed May 11, 1885. Serial No. 165,009.

To all whom, it may concern:

Be it known that I, ANDREW WELLARD, of Brooklyn, in the county of Kingsand State of New York, have invented an Improvement in Locks, of whichthe following is a specification.

This lock is especially intended for storedoors, and it contains asliding spring-latch, which can be operated from either the outside orinside of the door, and two or more oscillating bolts and eccentrics, bymeans of which the bolts can be projected or retracted. The eccentricsare loose upon the spindle, but are rotated by an intermediate disk withoffsets, and upon the eccentrics are spring-pawls. By turning thespindle in first one direction and then the other the bolts areprojected to lock the door, and they so remain until they are, moved bya further revolution of the spindle, which vcauses the eccentrics toswing the rocking bolts and withdraw them into the lockcase and allowthe door to be opened.

In the drawings, Figure l is a horizontal section through the spindleand bolts. Fig. 2 is a rear view with the cap-plate removed. Fig. 3 is asimilarview with the rocking bolts and eccentrics removed from the case.Fig. 4 is an elevation of the outer handle detached from the spindle.Fig. 5 is an end view of the same. Fig. 6 is an end View of the lock andcase. Fig. 7 is a view of the 'inside handle on the spindle. Fig. Sis aplan view of the same. Fig. 9 is a separate view of the intermediatedisk. Fig. 10 is an edge view of the same. Fig. 11 is a separate edgeview of one of the eccentrics and its connection to the rocking bolt,and Fig. 12 is a sectional view showing the swinging stop and notchedlifter.

The lock-case is made in the shape of a box, with a platankfriin'B, andremovable capplate C. The sliding spring-latchD passes at one endthrough the rim B, and it is guided by suitable studs inside thelock-case. d is the spring by which this latch is projected, and e is ahook on thelatch, by which the same is withdrawn.

F is a tubular spindle passing through the lock-case, and having Withinthe case a disk, j', with a claw or notch acting against the hook e; andG is a knob screwed onto the spindle F, by means of which this tubular(Model.)

spindle and disk are turned in drawing back the spring-latch.

H is a knob at the inner side of the door upon the spindle 7L, and k isa projecting arm acting within a notch in the spring-latch D, so thatsaid latch may be withdrawn by turning either the knob G on the outsideofthe door or the knob H on the inside of the door.

The movable separating-plate K is introduced into the lock-case, andaids in holding in place the parts described. Vithin the case is apivot-pin, i, upon which is placed the rocking bolts L M, which boltsare formed similar to anchors, and the ends project through mortises inthe rim of the lock. When the bolts are out of use, their ends areIiush,or nearly so,with the surface of the rim. V'Vhen the door islocked, one end of each rocking bolt is projected into a mortisein thedoor-frame or nosing. Between these rocking bolts there are metallicguide-platesZ Z', and a spring of india-rubber or other suitablematerial at u to apply by the plates Z Z to the surfaces of the rockingbolt sufficient press- 75 nre and friction to retain the rocking boltsin any position to which they may be moved. y

Within the tubular spindle there is a solid spindle, O, and within theknob G is a sliding coupler, g, having at its end a sectoral lng thatengages a notch similarly shaped in the end of the spindle O, and thereis a slot at one side of the knob G, and a pin and head g passingthrough this slot into the coupler g. Vhen this pin andconpler are movedendwise and the spindle passes into the sectoral mortise in the couplerg, the spindle will be moved by the handle, and the reverse.

Vithin a longitudinal groovein the spindle is the key p, and this ismade with a projectingblock at one place, and the end of the keyprojects from the inner end of the spindle, so that such key and itsblock can be slipped backward and forward. The block of the key,projecting above thesurface of the spindle, connects to said spindle theintermediate disk,R, which disk R surrounds the solid spindle,and itscentral opening or eye is notched to receive the block of the keyp, sothat said disk can be changed in its relative position to the rooindicator-arm G2, that projects from the knob G, by drawing back the keyand its block.

The disk R can either be turned upon its axis or the spindle turnedwithin it, so as to bring the block on the key p into a diiierent notchat the eye of the diskRfor altering the combination on which the lockopens.

and the rocking bolt there is a ring-strap and arm, so that when theeccentrics are rotated the bolts L M will be rocked upon'the pivot toproject or retract the respective rocking bolts.

Upon each eccentric there is a spring, s, which forms a pawl and againstwhich the off' set or shoulders upon the intermediate disk,R, operate.The operation of this lock is as fol` lows: When the pin g and couplergare moved to connect the knob G and spindle O, the disk R can berotated, and when turned in one direction the offset or shoulder uponsuch disk acts against the spring upon the eccentric T to turn sucheccentric, and by the eccentric` ring and its arm to move the rockingbolt M, after which the spindle O and intermediate disk, R, are to berevolved in the other direction, and the offset or shoulder upon thedisk acts upon the spring of the eccentric T, and partially revolvessuch eccentric, and by the strap and its arm the rocking bolt L isswung. If the lock is being unlocked, the movements last described willbe employed to swing the rocking bolts, so as to bring their ends withinthe rim of the lock. If the lock is to be locked` the movements asaforesaid are given in such a manner as to project the ends of therocking bolts.

There is to be a dial upon the door around the spindle O, and the sameis to be divided with suitable marks. I prefer to use divisions similarto a compass-card, and the pointer G", that projects from the knob G,indicates by this dial to the person havinga knowledge of the propercombination the place to which the spindle is to be turned in settingthe eccentrics and swinging the rocking bolts to open the door.

At the inner end of the solid spindle O an arm, o, should be attached,by means of which the spindle, intermediate disk, and the respectiveeccentrics can be turned when the door is open and the combinations ofthe lock are being altered, or it serves to lock or unlock the door fromthe inside.

I provide a swinging stop, w, pivoted at 3, and having a notched lifter,4, hinged to its outer end. This stop is directly over the slidingspring-latch, and does not prevent said latch being slid back by theinside handle, H, or drawn back by the talon or project-ion ou the diskf; but when the block w is lowered and rests upon the latch the disk canonly be partially turned back, suiciently to withdraw .the latch, butthe disk cannot be rotated after the stop w arrests the backwardmovement of the spring-latch, hence the swinging bolts cannot be actedupon or moved by the outside handle until the swinging stop is raisedand the sliding latch drawn back far enough to allow the disk toseparate from its hold upon the spring-latch. This prevents the swingingbolts being moved accidentally-while thelock is being used as a latchduring the daytime.

In cases where this lock isused on ware house-doors the spring-latchwill not be required.

If my improved lock is used with trunks or boxes having a catch ornosing that goes through a mortise in the lock-case,the rocking boltsare to enter mortises or pass above ofi`A sets upon the nosing or catchthat passes into the lock-case through the mortise.

I claim as my invention- 1. The combination, with the rocking bolts L M,of the eccentrics T T, the rings and arms connecting the eccentrics tothe rocking bolts, the spring-pawls on theeccentrics, the spindle O, thedisk R, and the movable key for connecting the disk to the spindle,substantially as specified.

2. The spindle O, the movable key within the groove in the spindle, andthe intermediate disk, R, in combination with the eccentrics T T', theirsprings, rings, and connecting-arms, the rocking bolts L M, interveningplates, and springs to apply friction to the rocking bolts,substantially as set forth.

3. The spindle O, the movable key within the groove in the spindle, andtheintermediate disk, R, in combination with the eccentrics T T', theirsprings, rings, and connecting-arms, the rocking bolts L M, the tubularspindle F, notched diskf, knob G, and spring-latch D, substantially asset forth.

4. The combination, in alock,`of the sliding spring-latch, D, the knobH, spindle and arm to operate the latch from the inside of the door, theknob G, tubular spindle F, and notched disk j', to operate thespring-latch from the outside of the door, the rocker-bolts L M,eccentrics and eccentric-rings for moving the rocker-bolts, the spindleO, intermediate disk, R, and spring-paw'ls for giving motion to therespective rocker-bolts, substanteally as set forth.
